Sunglasses are a kind of vision care products to prevent the strong stimulation of sunlight from causing damage to the eyes. With the improvement of people’s material and cultural level, sunglasses can be used as special accessories for beauty or personal style. Our eyeballs (lens) are very easy to absorb ultraviolet rays. The damage of ultraviolet rays to the eyes is invisible. To protect the eyes, we must always wear sunglasses.
Benefits of polarized lenses
When the light is reflected from the surface of the object, it has been partially polarized to produce glare. The opposite effect of glare enhances brightness and weakens color saturation; it makes the contours of objects blurred and makes eyes tired and uncomfortable. The polarizer is made according to the principle of polarization of light. It has a unique limited glare elimination function, which makes the vision clearer and natural, and has special effects on the driver, which can improve vision and increase driving pleasure.
Is the darker the sun lens, the better the UV blocking effect?
No, the function of the lens to block ultraviolet rays is due to the special processing (adding UV powder) during the manufacturing process, so that the lens can absorb harmful light such as ultraviolet rays below 400NM when the light penetrates, and it has nothing to do with the shade of the film.
